Kannastor is a Florida based company that specializes in high-grade herb grinders. Kannastor produces all types of grinders both single chamber and multi-chamber. Top quality anodized as well as medical grade aluminum is used in all of their grinders. This ensures they are built to last and not dull out. Their most popular line of grinders, GR8TR, uses the latest technology like interchangeable grinder plates and specifically engineered grinding teeth. This ensures a perfect and even grind each time. Even better, they also offer a lifetime warranty on manufacturing defects and broken teeth. Their multi-stage grinders allow for your herb to fall through the chambers, collecting along each step of the way. The pollen catcher catches the smallest particles of herb, that can be stored for later. Certain grinders like the Kannastor 4pc Grinder/Jar 3.0 have see through chambers, if you want to see the process first hand and know when the grinding chamber is full.
